It seems reasonable a similar thing happened here even as far back as the 1870s when the original construction was taking place.
Edit: Actually it was Seattle, you can still visit its old ground level: https://en.wikipedia.org/wiki/Seattle_Underground
A US city often overlooked for some intricate people explorable underground spaces is Cincinnati: https://www.visitcincy.com/blog/post/unmistakably-cincinnati...
Some of Cincinnati's underground exists from plans to build subway trains that never completed. I think that makes Cincinnati's particularly sad being that it constitutes a perpetually unfinished public works/public transportation project.
Relatedly to that, Atlanta also has a tiny underground leftover from passenger train lines that ended passenger travel decades ago (and so was turned into a mall, because America): https://en.wikipedia.org/wiki/Underground_Atlanta
But that doesn’t work if you need to support a skyscraper (not if you want it to stay upright), or dig a metro line, so new developments are now excavating the old rubble.
Mexico City is a quick plane ride from the USA, and while some of their ruins are buried, you can hop a short bus ride outside the city to walk among standing ruins of Teotihuacan, the largest city in the Western Hemisphere at the time Jesus walked on the Earth. It was 20 square kilometers whereas Rome at the height of the empire had only 14 square kilometers within the Aurelian Walls.
I've been on the Great Wall of China and all over the world and Teotihuacan was fascinating for me to see. Even more intriguing, no one knows who built it. Aztecs discovered it many centuries after it was abandoned and forever wondered about its origin.
...so what? Why would you compare "the size of Teotihuacan" to "the area enclosed in the Aurelian Walls"? Why not compare it to "the size of Rome"?
I can think of one reason you'd do this...
Arrowheads are an example of something that's not too difficult to find in the wild if you know where to look.
44,000 years of continuous human occupation. (Except for a brief period during the 20th century ..)
We used to smoke weed on the roman wall behind my friend’s high school. Very popular hangout spot. Lots of people using it for rock climbing practice (you’re not far off the ground and can climb laterally for hundreds of meters).
The local castle, about 1000 years old, is a popular makeout spot for teens.
And then we went to Paestum, which is an even older Greek settlement in Italy - with the original Greek temples still standing. Mindblowing, and I'm used to old stuff being around(a friend of mine lives in a house where a portion of it is a listed structure dating to the 12th century, it's just a bathroom and a storage room for them lol).
You didn't exactly say this, but I'd stop short of defining history around the existence of the current US government and structure. Ironically 250 years is probably longer than any continental European government has been around in its present state.
In terms of history as such, we have just as much history in the US as Europe does. Just ask the Native Americans / First People. There are lots of examples elsewhere in the conversation.
TBF, so do some folks in the U. S.; though in most cases, just barely.
It almost seems hard not to find ancient ruins. It then becomes a question of priorities and resource allocation.
> The students who found a way into the ruins weren’t the first amateur explorers to rediscover the site. Some of the graffiti scrawled on the walls of the villa dates to between 1920 and 1950, when the building was occupied by a religious order. Other markings are more recent, perhaps left by students at the high school

Unlikely. We know that the white marble statues that we have were once painted. Time turned them into what we see today. This room was surely vividly painted.
